Validation Update: AERONET-OC V3

SeaBASS Validation results have been updated with AERONET-OC V3 data


New Ordering and Download System

SeaBASS data downloads are now unified and distributed under the same system that manages NASA satellite Ocean Biology data

  • Placing a SeaBASS data order to download data now requires a NASA Earthdata login (you will be prompted to create one if you don't already have one)
  • Downloads will be fulfilled through an order manager

More info including links to illustrated instructions is found under Download and Order SeaBASS data


Earthdata forum transition

The Ocean Color Forum (including our subforum for Field Data - SeaBASS) has transitioned to the burgeoning Earthdata Forum (https://forum.earthdata.nasa.gov/). We encourage you to ask questions there and we look forward to interacting with you.

The new forum is organized using tags. Pick the "SeaBASS" tag to search for existing SeaBASS posts, or when you create a new post. There are a variety of search options; if you use the "Search By Tags" feature then SeaBASS is under the dropdown "Major Project". Other relevant tags include "Ocean" for Discipline and "OB DAAC" as the DAAC.

You can bookmark your favorite searches using your browser if you want a shortcut. Also, later this year a feature will be added allowing you to follow specific tags and receive email notifications whenever there is a new post.
